Sorry, I should have been more specific.
You were specific enough and Furball's information was right on. You need to take ownership of the files, but I'd recommend the drive so you don't run into anything else later.
First, display the Security Tab.
To display the Security tab
Open Folder Options in Control Panel.
Click Start, and then click Control Panel.
Click Appearance and Themes, and then click Folder Options.
On the View tab, under Advanced settings, clear Use simple file sharing [Recommended].
Second, take Ownership.
To take ownership of a file or folder
Open Windows Explorer, and then locate the file or folder you want to take ownership of.
Right-click the file or folder, click Properties, and then click the Security tab.
Click Advanced, and then click the Owner tab.
In the Change owner to box, click the new owner.
(Optional) To change the owner of all subcontainers and objects within the tree, select the Replace owner on subcontainers and objects check box.
You can also take ownership of the drive. If you select the drive and check the Replace ownder on subcontainers and objects you will get everything.
